MELTON MORRIS, OF DUTTON, ALABAMA.

FEED-REGULATOR.

To all whom it may concern:

Be it known that I, lVInL'roN MORRIS, a citizen of the United States,and a resident of Dutton, in the county of Jackson and State of Alabama,have invented certain new and useful Improvements in Feed-Regulators, of

which the following is a specification, reference being had to theaccompanying drawing.

This invention relates to improvements in feed regulators employedinconnection with grinding mills designed more particularly for thepurpose of producing a fine grade of corn meal and one of the principalobjects of the invention is to provide simple, reliable and eflicientmeans for adjusting the grinding stones and for providing means forshaking the hopper.

Still another object of the invention is to provide means for regulatingthe feed of the material to be ground, the feeding means being alsoutilized for shaking the bottom of the hopper to insure a continuous anduniform supply of corn to the grinding mechanism.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a grinding machine made in accordancewith my invention;

Fig. 2 is a top plan view of the same;

Fig. 3 is a vertical sectional View taken lengthwise of the main shaft;

Fig. 4 is a detail vertical sectional view taken through the hopper andits shaking bottom;

Fig. 5 is a detail sectional view showing the discharge spout;

Fig. 6 is a detail view showing the means for adjusting the grindingstones, one relatively to the other for grinding coarse and finematerial.

Referring to the drawings for a more par- Specification of LettersPatent. Patented Feb, 27, 1917,

shaft 4' is provided with' a ball bearing collar 8 and connected to saidcollar are L-' shaped bolts 9 which extend through a bearing plate lOmounted on one of .the'bars 2. A spiral spring 11 bears against thecollar 8 and against the plate at its opposite end.

The tension of the spring 11 may be adjusted lar 6 limits the movementof the shaft 4 in one direction.

The rotating grinding stone 16 is fast on the shaft 4 and the stationarystone 17 is mounted in the framework of the machine. The casing 18 isprovided with a downwardly inclined discharge spout 20 as shown moreclearly in Figs. 2 and 5.

One end of the shaft 4 is mounted in a bearing block 21 and a metalplate 22 bears against the end of the shaft 4 as shown more clearly inFig. 6, said plate being mounted in a slot or recess 23 in the bearingblock 21. Set screws 24 extend through the forward end 25 of the bearingblock 21, said set screws bearing at their inner ends against the plate22 to adjust the shaft 4 longitudinally and to regulate the distancebetween the stones 16 and 17 for grinding fine or.

which can be operated by means of a pivoted lever 30 to'regulate thefeed of the corn through the opening 31. The feed opening I of thehopper is located forward of the collar 6. The hopper ends in an obliquefront bottom portion a, as shown in Fig. 3.

Connected to the oblique bottom portion of the hopper is a shaking trayor member 32, said tray being connected to the hopper by means of a boltor pivot 33 which passes through the oblique front portion of the tray,while the opposite end of the tray is provided with an enlargement orlip 34 on the under side of the inner end thereof in the path of theribs 7 and when the shaft 4 is rotated the tray 32 is shaken up and downby means of the ribs 7 as will be obvious.

It will be seen that the tray 32 is supported at the forward end bymeans of the pivot 33, and at its rear end by means of the lip whichrides upon the collar and ribs.

From the foregoing, it will be apparent that the adjustment of thestones can be quickly made for grinding coarse or fine material; thatthe construction as a Whole is simple, cannot readily get out of order,7

can be manufactured at low cost and can be operated by an unskilledperson.

I claim: I

A feed regulator for a grinding mill comprising in combination, a frame,a shaft horizontally supported by said frame, an enlarged collar formedupon said shaft having spirally formed spaced feeding ribs said collarserving as a stop limiting the movement of said shaft in one direction,a hopper having a discharge opening located forward of said collar saidhopper ending in an oblique front bottom portion, a tray having anoblique front portion arranged for coaction With said oblique hopperbottom portion and ending in a lip at its inner end arranged toalternately ride upon said collar and ribs, and a pivot passing throughsaid oblique tray portion to said oblique hopper portion, whereby saidtray is pivotally supported at its forward end, as, and in the mannerset forth.

In testimony whereof I aflix my signature, in the presence of twowitnesses.

MELTON MORRIS.
